An elevator with a man inside, of gross mass 500KG, starts moving upwards with a costant acceleration and acquires a velocity os 2m/s after travelling a distance os 3m.Find the pull in the cables during the accelerated motion.

If the elevator, before stopping, moves with a constant deceleration from a constant velocity of 2m/s and comes to rest in 2 second, calculate the force exerted by the man of 75kg mass on the floor on the elevator.

    The pull of cable is 5.24x10^3N
    The force exerted by the man =75N
    Is it correct?

    first, find the acceleration.


    a=2/3 m/s^2


    force= m(g+a)=500(9.8+2/3) =
